expected in the answer. ii. Discuss a case where quicksort takes $O(n^2)$ complexity. In what way does this depend on the (CO:4) [5 marks] selection of pivot element? Elaborate.

Step 1
The sub-arrays are then recursively sorted. In the worst-case scenario, quicksort can have a time complexity of O(n^2). This occurs when the pivot element is consistently chosen as the smallest or largest element in the array. For example, let's consider an Show more…

Suppose we have an O(n) time algorithm that finds the median of an unsorted array. Now consider a QuickSort implementation where we first find the median using the above algorithm, then use the median as the pivot. What will be the worst-case time complexity of this modified QuickSort? Which one is faster for a data set of 1000 elements to be sorted? A) O(n^2 Logn) B) O(n^2) C) O(n Logn Logn) D) O(nLogn)

In QuickSort algorithm, what value of q does PARTITION return when all elements in the array A[p..r] have the same value? Modify PARTITION so that q = floor((p+r)/2) when all elements in the array A[p..r] have the same value.
